Works with the original A5 and X7 valves 02-V. You can tell if you have one of these original valves by measuring the length of the valve body itself. The original valve bodies are 1 & 1516" long whereas the new valves are 2" long.

This is the correct tombstone oring for the 1 & 15/16" short valve bodies.

On the A5's, the 02-V valve was used on all A5's including the 2011 remodel up to serial number 602597.
